the life span and the pathogenicity of amphistomes developing from cercariae indicae xxvi (paramphistomum epicilitum) were considerably reduced when the metacercariae were gamma-irradiated at 2 krad or 3 krad. the higher irradiation dose resulted in the complete absence of the flukes in infected animals. single vaccination of lambs and kids with 3000 metacercariae irradiated at 2 krad or 3 krad stimulated a significant degree of resistance against challenge with 5000 non-irradiated metacercariae ...

incidence of neutralizing antibodies to chandipura virus in domestic animals from karimnagar and warangal districts of andhra pradesh, india.

in order to determine the possible role of domestic animals in the outbreak of acute encephalitis associated with chandipura virus (cpv) among children in andhra pradesh in 2003, a serological survey of domestic animals was carried out during the epidemic in july 2003. out of 180 animal sera from highly affected areas of the karimnagar and warangal districts of andhra pradesh 33 (18.3%) had virus neutralizing (vn) antibodies to cpv. the positive animals consisted of pigs (30.6%), buffalos (17.9% ...

restriction enzyme analysis of vp7 gene of indian isolates of bluetongue virus.

the genome segment 7 of two indian isolates of bluetongue virus (btv) from avikanagar (btv-1-western india) and hyderabad (btv-untyped hyderabad-southern india) was amplified by rt-pcr using two sets of vp7 specific primers. a sequence of 1137 bp comprising the complete coding sequence of the vp7 gene from avikanagar isolate and a 1154 bp full-length sequence from btv-ut hyderabad isolate were amplified. further, restriction enzyme digestion of these full-length amplicons, using ecori, psti and ...

diversity analysis of sheep breeds from southern peninsular and eastern regions of india.

information is presented on the genetic diversity and relationship among six indian sheep breeds/populations belonging to the southern peninsular and eastern agroecological zones, based on microsatellite markers. parameters of genetic variation, viz., allele diversity, observed heterozygosity, gene diversity and population inbreeding estimates, were calculated for the six breeds. the allele diversity ranged from 6.40 to 7.92, whereas the gene diversity varied from 0.617 to 0.727. the highest all ...
